Diesel Organic Rankine Bottoming Cycle Powerplant Program: Volume II. Industrial Waste Heat Applications. Final Report

摘要

Several industrial processes and facilities were evaluated as possible sites to demonstrate the application of an Organic Rankine Cycle system (ORCS) using Fluorinol-85 as the working fluid to effect industrial waste-heat recovery. The economic applications for ORCS's using Fluorinol as the working fluid are in situations where the temperature of the waste-heat stream is between 400 exp 0 and 1000 exp 0 F. A literature review indicated that the greatest potential and economic advantage for an industrial application for the recovery of waste heat by means of an ORCS using Fluorinol as the working fluid is from the exhausts of high-temperature furnaces and boilers for six major industry categories. Together they expend 80% of the US annual energy consumption in the industrial sector. From these categories, four potential applications were selected, specific information about plant characteristics was obtained, and detailed performance predictions were carried out for an ORC waste-heat recovery system operating in these plants. In addition, the performance of the existing demonstration system hardware was predicted for two recommended applications, the petroleum refinery and the steel mill, utilizing only a portion of the available exhaust gas flow. Only nominal modifications would be required to make the existing hardware suitable for a demonstration program for either of these recommended applications. (ERA citation 07:044043)
